Bulgarian officials have identified two individuals — including a Canadian — who are suspected of involvement in a Hezbollah-linked bus bomb attack that killed five Israeli tourists last summer.

The men have been identified as Canadian Hassan El Hajj Hassan, 25, and Australian Meliad Farah, 32.

Earlier this year, Canada’s Foreign Affairs Minister John Baird said the Canadian in question was a dual national who resides in Lebanon, but did not identify him by name.

Then-immigration minister Jason Kenney said the man immigrated to Canada from Lebanon at a young age, obtained Canadian citizenship a few years later, and then returned to Lebanon when he was 12.

He has returned to Canada a few times but was not a “habitual” resident, Kenney said at the time.

On July 18 of last year, a bus exploded as it took a group of Israeli tourists from the airport to the Black Sea resort of Burgas. In addition to the five tourists, the suspected bomber — who has not been identified — and the Bulgarian bus driver were killed.

A statement posted on the Bulgaria Ministry of Interior website Thursday appealed to the public for information about the two named suspects.

The statement said between June 28 and July 18, 2012, the two men had registered themselves in hotels and rented cars in the region using fake names, including “Brian Jeremiah Jameson,” “Jacque Felipe Martin,” and “Ralph William Rico.”

Bulgaria’s former interior minister Tsvetan Tsvetanov has previously said that the pair used fake Michigan IDs to rent the cars but that they had entered the country with genuine Canadian and Australian passports.

“We have followed their entire activities in Australia and Canada so we have information about financing and their membership in Hezbollah,” Tsvetanov said earlier this year.

“A reasonable assumption can be made that the two of them were members of the militant wing of Hezbollah.”

Hezbollah, a Shiite militant group and political party, emerged in response to Israel’s 1982 invasion of Lebanon. It has denied involvement in the Bulgaria bombing.

The National Post has reported that the suspects received money transfers from Hezbollah and the explosives used were consistent with Hezbollah methods.

Further, the U.S. driver’s licenses used by the suspects were produced by a Beirut printer that has manufactured other fake IDs for Hezbollah, the newspaper reported.

Baird has previously said the attack in Bulgaria revealed “yet more evidence of the depravity of Hezbollah” and has urged the European Union and its partners who have not yet listed Hezbollah as a terrorist entity to do so.

On Monday, the EU agreed to put the armed wing of Hezbollah on its terrorism blacklist.

Canada listed Hezbollah as a terrorist entity under the Criminal Code in 2002.

An unclassified assessment of terrorist and extremist threats produced by CSIS last year said that Hezbollah “has had a presence in Canada” and that its supporters “conduct fundraising, procurement and intelligence activities in Canada, and are involved in organized crime, including fraud. Hezbollah continues to threaten retaliation against Israeli interests worldwide for the killing of key individuals in the past two years.”
